一、NEED与句子类型
(本条可参照ANY的用法。) NEED可用于：
1.否定句/含有否定意义的句子 1)否定句
含not/hardly/never/nobody等词语。 I needn’t say anything. He need hardly advise me. You never need tell me this or that. Nobody need help me. I don’t think he need come.(否定转移)
注：NEEDN’T的意思其实有三种，即不必要/不一定/不应该，视具体语境而定。 2)含有否定意义的句子
含only/but/all/before/than等词语。 He need only wait here. You need but consider the matter to understand its importance. That’s all that need be said.
Do not stay longer than you need. There was another hour before I need go out into the cold. 2.疑问句/表示疑问的从句 1)疑问句(包括否定疑问句) Need he say it again? 2)表示疑问的从句
I wonder whether/if I need see her. 3.条件句
含if/unless等词。
If he need come, he will. 本条要点简单概括起来就是，NEED不能用于肯定句。以下的各种用法也遵循这条规则。
二、NEED与时态 1.现在时
NEED常用于现在时。 You needn’t stay. 2.将来时
You needn’t have your blood pressure taken tomorrow. 3.过去时
NEED的过去式仍然是NEED。 1)过去时间由一过去时间状语表示 He need not come yesterday. 2)过去时间由另一过去时动词表示。 All he need do was to inquire. It was clear that he need never trouble to get up at seven again. I told him he needn’t be in a terrible fix. 注：表示过去的NEED常用于间接引语中。 (本条可参照must的用法)
三、NEED与虚拟语气 1)NEED用于虚拟条件句
(本条可参照虚拟条件句的构成及用法。) If money were useless, we need not struggle for it. If you had been careful enough, you need not have suffered. 注：本条用法较为少见。
2)NEED单独使用：NEEDN’T HAVE DONE (本条可参照SHOULDN’T HAVE DONE的用法。) You need not have worried. 注：NEED HAVE DONE的形式较为少见
Need you have scolded him so severely for his bad work? He had done his best.(否定意味)
He need have gone and sent that letter in person.(实际上没有做)
四、NEED与推测
NEEDN’T表示“不一定”。 (本条可参照must/can的用法。) 1) NEEDN’T+BE
It needn’t be hot in Florida now. 对比：
It can’t be hot in Florida now.(一定不) It must be hot in Florida now.(一定) 2) NEEDN’T+HAVE DONE
He need not have seen much of the world, though he is an old man. 对比：
He can’t have seen much of the world, for he is just a little boy. He must have seen much of the world, for he has been traveling so widely.
五、NEED与问句 1)反意疑问句的构成 You needn’t go, need you? 2)答句的构成 --- Need he go? --- Yes, he must/has to/needs to. --- No, he needn’t.
(本条可参照must的用法)
六、情态动词NEED与实义动词NEED 1)使用范围
作为实义动词的NEED有人称、数和时态的变化，使用范围更为广泛，不受句子类型和时态的限制。在肯定句、过去时和将来时的句子中，一般使用作为实义动词的NEED。
He needs to see a doctor straightaway.(此处needs to不能换做need，因为本句是肯定句)
Will he need to start earlier? 注：
NEED TO BE DONE与NEED DOING可以互换，后者更为常用(这里的NEED均为实义动词)。 2)含义差别
NEEDN’T HAVE DONE与DIDN’T NEED TO DO表示“不必要”的时候，在意义上有所差别，前者表示“本不必做„„”，实际上已经做了(NEED为情态动词);后者单纯地表示“不必做„„”(NEED为实义动词)。
教学的方式要以教学的任务和内容、学生的年龄特点和心理需求，灵活多变地加以应用。小学生容易注意力不集中，为了引起学生的注意力并激发学生的学习积极性，在教学情态动词can 的时候，教师画出下列简笔画：
我边画简笔画边说: I can do a lot of things. What can I do? Do you want to know. Let me tell you. I can play table tennis.(画出第一幅图示并鼓励学生说出动词短语：play table tennis) . I can play the piano.(画出第二幅图示并鼓励学生说出动词短语play the piano). I can stand on my head.(画出第三幅图示并鼓励学生说出动词短语stand on my head). 然后我叫了五位学生，让他们做动作来告诉大家。我又问：What can he /she do? 让他们说出:I can…….引出另外五个短语：play football, swim, roller blade, ski,ride a horse.接着让学生根椐学过的动词短语用句型Ican ….I cannot….个自写出自己会做的事情和不会做的事情. 然后让学生利用句型:What can I do? Can you…? Yes, I can.或No I can’t. 互猜彼此会做的事情和不会做的事情。这样可以让学生所学语言产生兴趣，从而激发学生的学习欲望调动学生的学习积极性。
这样通过大量的、反复的、多种形式的操练，要求学生在量中求质，在速度中求准确。
我认为，为了有效地利用练习的时间，提高练习的效率，教师在组织练习时，要分秒必争，争取在有限的时间内，加大练习的强度和密度。
